Valve Supply for Power Plant Project – Engineering & Execution Overview
TABLE OF CONTENTS
Scope of Supply
The supply scope included:
- Gate valves for isolation in main steam and feedwater lines
- Globe valves for flow regulation and control applications
- Check valves for backflow prevention
Typical configurations included:
- Pressure seal bonnet design for high-pressure service
- Butt weld end connections for pipeline integration
- Forged and cast materials based on size and pressure class
Actuation was applied where required for operational control and system integration.
Execution Approach
1. Technical Clarification Phase
Before production:
- Datasheets were reviewed against system requirements
- Critical parameters (pressure, temperature, media) were confirmed
- Any ambiguities were clarified to avoid misinterpretation
2. Production Planning
Production was scheduled based on:
- Valve type and size range
- Material availability
- Machining and assembly requirements
Critical items were prioritized to align with project milestones.
3. Manufacturing & Assembly Control
Key control points included:
- Machining tolerances for sealing surfaces
- Assembly alignment for pressure sealing components
- Verification of actuator mounting interfaces
Quality Control, Delivery Coordination & Project Execution Outcome
Quality & Testing
Testing and inspection included:
- Hydrostatic pressure testing in accordance with API 598
- Seat leakage testing based on valve type and service conditions
- Dimensional and visual inspection
Material traceability and documentation were maintained throughout production.
Delivery & Coordination
Delivery planning was aligned with production progress:
- Batch delivery was arranged based on installation sequence
- Packaging was designed for export conditions (sealed protection + wooden crates)
- Shipment schedules were coordinated with project timelines
Project Outcome
The project was executed with a focus on:
- Accurate engineering alignment
- Controlled manufacturing process
- Reliable delivery scheduling
This ensured that the supplied valves were not only compliant with specifications, but also suitable for actual operating conditions within the power plant system.
